How to graph y = 2 - 2 x ?

${\displaystyle y=2-2x}$ is the same as ${\displaystyle y=-2x+2}$, which is the slope-intercept form of a linear equation, ${\displaystyle y=mx+b}$, where ${\displaystyle m}$ is the slope and ${\displaystyle b}$ is the y-intercept. In the given equation, ${\displaystyle m=-2}$ and ${\displaystyle b=2}$.
Finding at least two points on the graph, placing those points on the graph, and then drawing a straight line through those points are all necessary steps in graphing a linear equation.
To find the points, pick values for ${\displaystyle x}$, and solve for ${\displaystyle y}$ using the equation ${\displaystyle y=-2x+2}$.
Point 1
${\displaystyle x=0;}$${\displaystyle y=2}$
Point 2
${\displaystyle x=1;}$${\displaystyle y=0}$
